Abstract (en)
An electric ball valve, comprising: a shaft portion (216), a magnetic ring (217), and a Hall sensor (245), the Hall sensor (245) being in electrical and signal connection with a circuit board (241), the shaft portion (216) being connected to an output shaft (237) and capable of rotating along with the output shaft (237), the magnetic ring (217) being sleeved on the radial periphery of the shaft portion (216), and the magnetic ring (217) being capable of rotating along with the shaft portion (216); and a cushioning portion, the cushioning portion directly or indirectly abutting against an end of the shaft portion (216). Also provided is a method for manufacturing an electric valve. The present electric ball valve is provided with the cushioning portion at the end of the shaft portion (216), thereby facilitating reducing downward plays of the magnetic ring (217) and the shaft portion (216) in the axial direction during rotation along with the output shaft (237), and thus facilitating improving the detection prevision and stability of a detection assembly and improving the control prevision of the electric ball valve.
